Crow-Armstrong’s first career grand slam in the seventh inning of Friday night’s 13-6 win over the Cincinnati Reds made him the first Cubs player since runs batted in became an official stat in 1920 to have two games with at least six RBIs in a calendar month.

Crow-Armstrong didn’t miss and pulled the pitch down the line, but it wasn’t immediately clear if he stayed back on it enough to keep the ball fair.
